ATTACHMENT FOR SPINNING-MACHINES.

SPECIFICATION forming part of Letters Patent No. 500,758, dated July 4, 1893.

Application filed November 16, 1892- Serial No. 452,228- (No model.) Patented in England June 11 1892, No. 11,020, and in Belgium June 13,1892,No.'100,096.

.To all whom it may concern.-

Be it known that we, LOUIsE OROEs, ED- OUARD RonnNBAoH MERGAERT, and J EAN LAPIN, subjects of the King of Belgium, re-

siding at Roulers, in the Kingdom of Belgium,

have invented a certain new and useful Improvement in Attachments for Spinning-Machines, of which the following is a specification.

The invention has been patented in Belgium, No. 100,096, dated J une 13, 1892, and in England, No. 11,020, dated June 11, 1892.

Our present invention is an improvement upon the device shown and described in Let- 5 ters Patent of the United States granted to us September 6, 1892, No. 482,003.

Our object is to secure a more positive action which will effect the removal of the broken thread from the drawing or stretching 2o cylinders quicker and, further, to prevent undue strain on the thread by employing a counterpoise only of sufficient weight to throw the parts in connection upon the severing of a thread the full and complete operation being accomplished by means operated positively from some moving part of the spinning frame.

In the accompanying drawings Figure 1 is a side elevation of our improved device. Fig. 2 a front elevation and Fig. 3 a plan view of 0 the same.

The upper arm G having a hooked end H is intended to strike against and remove the thread when it breaks as is the upper arm in the patent before mentioned. Likewise the lower arm N having a hooked end 0 is intended to engage the thread below the roller or cylinder. Both of these arms are on a rock shaft F having a socketed lower part M fitting over the stud P. The arms are held to one side when the thread is intact by the lower arm engaging said thread, a counterpoise or weight K being provided tending constantly to force the arms against the thread to move the same aside. The counterpoise acts upon the rock shaft.

Instead as in the former application of using the weight for throwing the arms entirely to one side and thus removing the thread from between the rollers we now merely use the weight to turn the rock shaft F sufficiently upon the breaking of a thread to throw the arm R around so that its finger r will engage with the threads of the worm Swhich positively and rapidly moves the arm R farther in the same direction thus turning the spindle F and with it the upper arm to move the broken ends of the thread entirely from the engagement with the rollers. By this means a very light weight may be used as it is only necessary to throw the finger 4" into engagement with worm S and thus the strain on the yarn under normal conditions is reduced to a minimum. The worm S is driven constantly from any suitable part of the machine and when once the finger 'r is engaged by the worm the action goes on rapidlyand positively. When the parts are in normal position with the arms engaging with the unbroken thread the finger 7' lies in the open space between the end of the worm thread and the end collar S. The space is sufficiently large to permit the finger r to have slight oscillating movement without engaging with the thread of the worm. A straight collar S is arranged at the other end of the worm.

Any number of rock shafts and worms may be employed.

In resetting the device the attendant has only to lift the rock shaft from its stud P slightly so as to free the finger r from the worm when the rock shaft may be turned swinging the parts back again into the posi tion indicated in Fig. 3.

We claim-- 1. v In combination, the rock shaft having the arm for engaging the thread and adapted to turn when the thread breaks the arm R also connected with the rock shaft, and the constantly operating means normally disengaged from the arm B, and arranged in line with the movement thereof to engage and operate the same upon the breaking of the thread, substantially as described.

2. In combination, the rock shaft having the arm to engage the thread and adapted to turn when the thread breaks, the arm It, all so connected with the rock shaft and the positively operating worm arranged inv the line of movement of the arm R, to be engaged thereby when the rock shaft turns upon the breaking of the thread, substantially as described.

3. In combination, the rock shaft having the arm to engage the thread and the arm R, the Worm arranged in the line of movement of the arm R, to be engaged thereby when the rock shaft turns upon the breaking of the thread said rock shaft with its arm R being longitudinally movable to disengage the arm R, from the worm, substantially as described.

4. In combination, the rock shaft, having the arm to engage the thread and the arm R, the positively operated device in the line of movement of the arm R, to be engaged thereby when the thread breaks, the said rock shaft,

having a socketed lower portion, and the supporting stud P adapted to said socket portion whereby the rock shaft may be moved longitudinally to disengage the arm R, from the Worm, substantially as described;

In testimony whereof we have signed this specification in the presence of two subscribing witnesses.
